We had a soil blowout last summer during the big rain on July 2, 2013. The ditches got filled in with dirt and water has been all over the trail making it very slippery. We decided to fix the blowout area with large boulders and do some surgical ditching to keep the water moving.
The first photo shows Key Construction filling in the erosion site with large boulders. This hole was caused by flash flooding this summer. Second photo shows the finished work. Ditches were cleaned on both sides of the trail near the washout. Hardpack was spread on the surface of the trail near the affected part of the trail. The 3rd photo shows some ditching with a backhoe. The fiber optic cable is somewhere below… nerve racking work The job is now done. We are working with the NHDOT next week to see if we can lessen the erosion effects of storm water on the trail.
We are happy to let you know that ditching and repairing the trail just west of riverside cross walk on Riverside Road in Lebanon is finished. Dana Key Construction took on the Job which was funded by FNRT. Large rocks the size of a small car were placed in the the washout section, the ditches were cleaned and some hardpack was placed on top of the trail for traction. Next we will be asking NHDOT if there is a way to keep the water from coming over the bank from RT 4 and onto the trail. Both sides of the trail in that section are very steep so that surface water comes down the slopes at a great velocity. Ken.
